int main() {
  Box aBox = { 1, 2, 3 };
  Box* pBox = &aBox;
 
  Box* pBox2 = new Box;
  pBox2->height = pBox->height+5.0;
  pBox2->length = pBox->length+3.0;
  pBox2->width = pBox->width+2.0;
  cout << "Volume of Box in the free store is " << pBox2->volume() << endl;

  delete pBox;
  delete pBox2;
  return 0;
}

Volume of Box in the free store is 128
